AI Technical Summary

Benefits of technology

The invention is a gas spring that can absorb movements that occur perpendicular to its main operating axis.

Problems solved by technology

The dies wherein these gas springs are installed tend to have guidance suitable to the functions thereof; however, specific parts thereof can have slight horizontal oscillations within its vertical movement actuated by the press.
Nevertheless, this solution presents the drawback that the surface can make a print on the die, deforming it and reducing the operational stroke.

Embodiment Construction

[0007]The gas spring object of the invention is of the type which comprises a hollow cylindrical body with one open end and a piston rod located inside the hollow cylindrical body which can be moved therein through its open end. The spring further comprises a sliding element connected to the free end of the piston rod and laterally displaceable with respect thereto, so that it permits the absorption of movements perpendicular to the operating axis thereof.

[0008]The spring that is object of the invention further comprises a connection element between the sliding element and the piston rod which comprises an internal part which is located inside the piston rod and an external part which protrudes from the free end of the piston rod. The sliding element is also situated on the free end of the piston rod, and the sliding element and the connection element are configured so that the sliding element is laterally displaceable with respect to the external part of the connection element.

Abstract

The invention consists of a gas spring which can absorb movements perpendicular to its operating axis. To do that, it has a hollow cylindrical body (1) with an open end, a piston rod (2) located in the hollow cylindrical body (1) which can be moved therein and a sliding element (3) connected to the free end of the piston rod (2) and laterally displaceable with respect thereto. It also has a connection means (4) between the sliding element (3) and the piston rod (2) which comprises an internal part which is located inside the piston rod (2) and an external part (5) which projects out of the free end of the piston rod (2), the sliding element (3) being situated on the free end of the piston rod (2) and the sliding element (3) and the connection means (4) being configured so that the sliding element (3) is laterally displaceable with respect to the external part (5) of the connection means (4).

Description

OBJECT OF THE INVENTION[0001]The object of the invention is a gas spring which can absorb movements perpendicular to the operating axis thereof.BACKGROUND OF THE INVENTION[0002]Gas springs are applied during sheet shaping processes, limiting the stress exerted thereon and making it possible for there to be displacement of the shaping tools with a slight increase of force.[0003]The dies wherein these gas springs are installed tend to have guidance suitable to the functions thereof; however, specific parts thereof can have slight horizontal oscillations within its vertical movement actuated by the press. These types of horizontal oscillations are generally caused by floating plates used to hold the sheet piece while work is done thereon, or due to vibrations of the die itself when very localized stresses are made on a part thereof and not completely offset.[0004]In order to resolve this problem, the use of a spherical surface on the end of the mobile axis is known which permits a cert...
